Pears are a crisp, fiber-rich fruit that supplies a modest amount of plant protein. This pear protein calculator converts any portion — small, medium, large, or a cup measurement — into grams of protein, protein calories, and its share of a 50 g daily protein target. It is a convenient companion for meal planning, macro tracking, and anyone curious about the nutritional profile of everyday fruits.
Use the presets for common servings like one medium pear or 100 g, or enter your own quantity and portion size. The protein value is pre-filled from USDA data and can be adjusted to match a different database or product label. The results panel shows a step-by-step derivation, making it easy to verify every number. Whether you are a dietitian, fitness enthusiast, student, or home cook, this tool gives you a quick, reliable estimate of pear protein.

How to Use the Pear Protein Calculator
Start by choosing a portion. The dropdown includes common pear sizes — small, medium, large, 100 g, and cup measures — and each option carries its average weight in grams. Enter a quantity of that portion, then adjust the protein-per-100g field only if your food database or product label gives a different value. Click Calculate protein and the results panel will show total protein, protein per 100 g, protein calories, and the percentage of a 50 g daily value.
How the Calculation Works
The tool converts your portion into a total weight, then applies the protein density of raw pear. Using USDA data, raw pear contains roughly 0.36 g of protein per 100 g. Protein contributes about 4 kcal per gram, so the calorie estimate is simply protein grams multiplied by 4. The daily-value percentage is based on a 50 g reference target, a common benchmark for general protein labeling discussions.
The same calculation method is used in most nutrition analysis workflows: weight × nutrient density = nutrient amount. For a detailed nutrient profile, see the USDA FoodData Central entry for raw pears.
Worked Example
Suppose you eat one large pear weighing 230 g. Using the default 0.36 g protein per 100 g:
- Total weight: 1 × 230 g = 230 g
- Protein: (230 ÷ 100) × 0.36 = 0.83 g
- Protein calories: 0.83 × 4 = 3.3 kcal
- Share of 50 g target: (0.83 ÷ 50) × 100 = 1.7%
Standard Pear Portion Weights
| Portion | Average Weight | Protein (approx.) |
|---|---|---|
| Small pear | 148 g | 0.53 g |
| Medium pear | 178 g | 0.64 g |
| Large pear | 230 g | 0.83 g |
| 1 cup sliced | 140 g | 0.50 g |
| 1 cup chopped | 161 g | 0.58 g |
Tips and Accuracy Notes
Pear size and variety affect the result. A Bartlett, Anjou, or Bosc pear can differ slightly in water content and density, which changes the protein per gram. The values used here are averages from USDA analysis of raw pear. For the closest estimate, weigh your pear on a kitchen scale and enter grams directly by choosing the 100 g option with a custom quantity.
- Do not confuse the weight of the whole pear with the edible portion — the values in this tool refer to the flesh with the core and stem removed.
- If you are tracking a specific product, such as canned or dried pear, use the protein value printed on the label instead of the raw-fruit default.
- Protein is a minor nutrient in pears; the tool is best used as part of a broader macro plan rather than a protein-focused food choice.
Frequently Asked Questions
Are pears a good source of protein? No. Pears are mostly carbohydrate and water, providing only about 0.36 g of protein per 100 g. You would need to eat a very large quantity to make a meaningful protein contribution.
Can I use this for canned or dried pears? Yes, but change the protein-per-100g value to match the nutrition label. Dried pears are more concentrated and have a higher protein density by weight.
Why does the daily value percentage seem so small? Because a typical pear contains less than 1 g of protein, while the 50 g daily reference is much larger. This is normal and expected for most fruits.
Where do the portion weights come from? The weights reflect common USDA portion estimates for raw pear, rounded to whole grams. For more detailed data, visit the USDA MyPlate fruit group guidance.
